Curved Mascara Applicator Stem Geometry for Corner Eyelash Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mascara applicators often hinder easy application to the small eyelashes at the corner of the eye due to their design, which can be cumbersome and limit the user's ability to achieve various makeup effects.
Innovation Solution
A curved stem applicator with a unique geometry, forming an elbow at the junction with the applicator member, allows for ergonomic handling and varied application angles, featuring a core with application elements that facilitate reaching the external and internal corners of the eye without stem interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rectilinear stem applicator is used, then the structure is simple and easy to manufacture, but it hinders easy application to small eyelashes at the corner of the eye due to stem interference
Solution Approach 1:
The stem is curved on the distal side to form an elbow shape, creating clearance between the stem and applicator member. This curvature allows the applicator to reach corner eyelashes without stem interference while maintaining ease of manufacture through simple geometric modification
2Adaptability or versatility
If a curved stem forming an elbow is used, then ergonomic handling and varied application angles are achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The elbow-shaped curvature provides multiple application angles and ergonomic handling by positioning the applicator member clear of the stem. The curved geometry is achieved through standard molding techniques, balancing manufacturing feasibility with enhanced versatility
3Ease of operation
If the applicator member extends in line with the stem, then the structure is compact, but it limits the user's ability to reach external and internal corners of the eye
Solution Approach 1:
The elbow-shaped curvature creates spatial clearance between the stem and applicator member, enabling the user to reach external and internal corners of the eye. The curved configuration optimizes the spatial arrangement without excessive volume increase

AI summary
The present invention relates to an applicator (2) for applying a cosmetic, makeup or care, product (P) to human keratin fibres, in particular the eyelashes and/or eyebrows, having a stem (7) and, at the distal end thereof, an applicator member (8) having a core (10) that extends along a longitudinal axis, wherein the stem (7) has a rectilinear portion (7a) that extends along a rectilinear longitudinal axis (Y) and a curved portion (7b) that extends along a curvilinear longitudinal axis, the distance between the longitudinal axis (Y) of the rectilinear portion (7a) of the stem (7) and the longitudinal axis of the curved portion (7b) of the stem (7), measured perpendicularly to said axis (Y), increasing in the direction of the distal end of the stem (7), along at least a part of the length of the curved portion (7b), and the distance between the longitudinal axis of the core (10) and the longitudinal axis (Y) of the rectilinear portion (7a) of the stem (7), measured perpendicularly to said axis (Y), decreasing by going away from the distal end of the stem (7), along at least a part of the length of the applicator member (8).
